Hm, I guess it's much simpler than that. I must not be understanding something about covariance. The following code produces the same error message (it has nothing to do with nestedness or shared classes):

interface Interface
{
    Interface getNext();
    const(Interface) getNext() const;
}

class Implementation : Interface
{
    Implementation getNext()
    {
        return null;
    }

    const(Implementation) getNext() const
    {
        return null;
    }
}

This is a compiler bug. It works if 'Interface' is changed to an abstract class.
